V-Belt Tension &
Replacement
V-Belts stretch and wear with use, so check the
tension on a monthly basis to ensure optimal
power transmission. Replace the V-belts if they
become cracked, frayed, or glazed.
On the Model G0602, the
low range V-belt ten-
sion is controlled by a tensioner between the
secondary drive pulley (B) and spindle (C) pulley.
The
high range V-belt between the spindle (C)
and motor (A) pulleys is tensioned by the motor.
On the Model G0752, V-belt tension is controlled
by a tensioner between the spindle and motor
pulleys.
